The Delhi metro offers all the benefits of a typical public transport system plus a few added aspects that make it stand out as a unique, cutting-edge model. It has been credited for being punctual, safe, and environmentally friendly.

Prior to the Delhi Metro, the capital city suffered from lack of an adequate, reliable, and safe public transport system. The metro is the first effective solution to the city's transport problems - catering to all classes of people with an affordable and practical solution.

Delhi is a highly populated city that is expected to see a rise in motor vehicles to 35 lakh by 2011. This growth will exasperate the current road congestion and pollution; hence, in this context, a metro system is a necessary alternative for daily commuters.

The number of passengers on the Delhi metro has greatly increased since its launch - from a mere 20,000 commuters at its outset, to one million, and it is expected to double by the end of 2010. In every train, there is a compartment reserved for women. Moreover, the Delhi Metro is the world’s first railway project to be registered by the United Nations Framework Convention on Climate Change under the Clean Development Mechanism. It has claimed carbon credits, amounting to 1.2 crore annually, for the use of a regenerative braking system. The metro also boasts convenient facilities such as token dispensation machines, personal assistance for physically challenged persons, ticketing and passenger control through an Automatic Fare Collection System, and feeder bus connectivity.
